To all whom it may concern:

Be it known that I, MIKE SIKQRA, a citizen ot the United States, residing at Robins, in the county ot Guernsey and State of Ohio, have invented certain new and useful Improvements in a Locking Means for Demountable Rims, of which the tollowing is a specification.

This invention relates to improvements in means tor locking demountable rims on the telly ot a vehicle wheel in such a manner as to prevent any possibility of the rim from moving circumterentially on the telly thus preventing any possiblity ot the valve stem becoming broken. I

Another important object of the present invention is to provide a locking means tor demountable rims ot the above mentioned character, which-may be readily and easily inserted in position between the rim andthe telly ot the vehicle wheel, additional means being provided for securing the locking means in place against accidental disengage- IDS 7 therewith.

ment.

A. still further object of the invention 18 to provide a locking means tor demountable rims ot the above mentioned character,

which is simple in construction, inexpensive, strong and durable and furthermore adapted tor the purposes for which it is designated.

Other objects and advantages of this invent-ion will become apparent during" the course of the tollowing description.-

In the accompanying drawing forming a part of this application and in which like numerals designate like parts throughout the samec Figure 1 is an velevational View of a vehicle. wheel showing my invention associated Figure 2 is a sectional view taken approximately on line 22 of Figure 1, and

spaced intervals such as are shown at 6 and 7 in the drawing. These grooves taper gradually from one side of the telly and rim respectively to the opposite side thereof to provide tapered sockets or pockets tor the purposes to be presently described.

Adapted to be driven in each of the sockets or pockets formed by the registering grooves between the telly and the rim is the wedge shaped key or block 8. Each of the locking keys is held in position inits respective socket by means ot a cooperating lug 9 which is supported on the threaded endot a bolt 10 which extends through the telly 1. The

nut 11 is provided torsecuring the lug on the threaded end of the bolt and-the manner in which the .keys or blocks are securedin locked engagement with the telly and rim is clearly illustrated in Figures 1- and 2 of the drawing.

When the parts are arranged as shown in the drawing, the rim will be prevented from moving, circumterentially around the telly thereby preventing any possibility of the valve stem becoming broken as frequently happens with the demountable rims and tastening means now in use on pneumatictire wheels. or blocks also will eliminateto an appreci= ableextent a lot ot unnecessarynoise caused The provision ot the locking keys by the swinging between the rim and the telly with the retaining'lugs now in use.

The simplicity in which my device is constructed enables the parts to be readily assembled or disassembled as the case may be.

The provision ot the locking block retaining lugs turthermore prevents any possibility ot the same becoming disengaged from the sockets in which the same are wedged and thereby will hold the rim and the pneumatic tire thereon in a rigid position onthe telly ot the wheel.

While ;I have shown the preferred. embodiment of my invention, it is to be understood that various changes in the size, shape and arrangement ot parts may be resorted to without departing from the spirit of the invention and the scope of the appended claim.

Having thus I claim is In a structure of the class described, a wheel telly, and a rim mounted thereon, the

meeting. faces of the rim and telly having.

transversely extending registering grooves extending from side to side and torming described the'invention, what open ended sockets, said sockets being polygonal in cross section, and arranged at spaced intervals around the circumference of the telly and rim, a wedge-block removably fitted into each socket and having its ends exposed at each end of the socket, said Wedge being of a size and shape to snugly fit Within the socket, bolts extending transversely tl'irough the telly, lugs fitted upon the threaded ends of the bolts and engaged I with said Wedge blocks, and retaining nuts for said lugs.

In testimony whereof I affix my signature.

MIKE SIKORA.
